Re it known that l, lltl'iLLrAM J. EDWARDS, of the cit-y of lvlontreelD Province oi' Quebec, Dominion of Genade, a. subject of the King cit' Greet Brituim here invented certe-in new and useful "improvements in Burners; and l do' hereby declare that the followingA is a full, clear7 and exact description thereof.

lily invention relates particularly to gn; 1 0 torches for burning oil peint end :tor biezine.y soldering and Welding certain metals; und has for its object to provide e. readily controlled hot llame.

More speciicelly stated the invention consists oit' e. torchincluding ineens adjusting; the thune 'tor use to burn peint from floors and the sides of railway eers end other surfaces. und by e Variation of the 'Heine adapt it for brezing brass, steel and malle,- able iron, Welding cast iron end closing breaths end patching' holes in iluminuni parts. rllhe principal feature oli my 'torch is e valvular bushing or sleeve the interior whereof divided by L plug` into `sepzufite cl'lzunbers one Yfor oir or oxygen end the other ifm.' ordinary coal ges. For the proportioning of the air and oxygen relatively to the coal l employ e pipe ot diminutiye bore which is carried by the plug in such :1. man ner that it communicates with the oir end oxygen chamber and projects through the gas chamber With its tip l protruding slightly beyond the mouth ol" the torch. A tip or nozzle carried slidebly by the mouth of the torch presents :1 -chamber in which the ges and air or oxygen mix, and permits oi? ready adjustment or the llame 'lier the pui poses just mentioned. The construction or" the torchj as hereinafter set forth, permits of 40 simultaneous adjusting` of the air or oxygen and ges or the regulation ol the ges alone with e steady supply. of compressed nir or preedjusted oxygen For full comprehension, l'ioweveri ol my in- Al vention reference must be hed to the eecomponying dra-Wings in which siiniler re ,terence characters intricate the some parts :ind wherein: v

is of a length to prevent complete closing oli the ports thus keeping a pilot-light burning even when the sleeve 1s turned to closed position.

Operation.

l/Vhen yit is required to burn paint from large surfaces as lloors, walls, the sides ot railway cars and the like the nozzle o is ein, ployed and it is adjusted to position with its mouth slightly in advance of the mouth of the air pipe n. According to the proportion ot' gas used, the larger the proportion oit gas the greater capacity oi chamber required between the mouth oit pipe n and the mouth r)This chamber is Where the mixture of gas and air or gas and oxygen takes place. Grdinary coal gas is supplied to the connection 7c by a flexible pipe and a compressed air supply is connected to connection g by a flexible pipe, While the bore j is plugged as indicated in Figure l. rlhe torch may then be used freely and the paint of these `Wide surfaces is rapidly removed.`

lll? desired the plug may be removed from j and put in g and the compressed air connected atv/j for convenience in handling the torch.

When brazing brass, steel and malleable iron or Welding cast iron the nozzle g is used and the connection g is plugged While an oxygen gas supply `controlled by a tap y is connected to connection j inplace of the compressed air and the connection of ordinary coal gas at 7c is maintained. lll/hen repairing a broken aluminum device the arrangement just described is employed, the

heat beingl sufcient to make the edges of the break run together and be Worked until united a stick @it aluminum being used to lill in; or a hole maybe patched by dropping aluminum heated in the same manner onto a non-combustible anvil inserted beneath the part With the hole the edges of the hole being simultaneously raised to a Welding heat.

The valvular bushing or sleeve Z isreadily adjusted by the knurled head fand as above described the torch-is adapted to have this sleeve function to either adjust the air Aor oxygen and gas simultaneously when the connections are at j and 7c or permit 'tree supply of the air and regulated supply ot the gas as when the connection is at g and 7c. The use of the plug m dividing the interiorof the valvular sleeve into separate end chambers and carrying the pipe n is essential to this regulation; and the fact that .the plug and pipe n are carried by this valvular bushing or sleeve enables a. simple construction to perform the functions described.

l/Vhat I claim is as follows:

l. A torch consisting of a tubular body portion with a tubular neck of' less diameter than the body portion, a sleeve rotatably mounted Within the bodyr portion, means portion having registering ports commu.
